  • The Ridesharing Revolution: Economic Survey and Synthesis
    The Ridesharing Revolution: Economic Survey and Synthesis Robert Hahn and Robert Metcalfe* January 10, 2017 Paper prepared for Oxford University Press Volume IV: More Equal by Design: Economic design responses to inequality. Eds. Scott Duke Kominers and Alex Teytelboym. Abstract Digital ridesharing platforms, such as Uber and Lyft, are part of a broader suite of innovations that constitute what is sometimes referred to as the sharing economy. In this essay, we provide an overview of current research on the economic efficiency and equity characteristics of ridesharing platforms, and provide a research agenda that includes an examination of the natural evolution toward driverless cars. We have three main findings: first, relatively little is known about either the equity and efficiency properties of ridesharing platforms, but this is likely to change as companies and researchers focus on these issues. Second, we may be able to learn something about the likely diffusion and benefits of these technologies from experience with other policies and technologies. Third, while we believe these platforms will do substantially more good than harm, the measurement, distribution, and size of the gains from these technologies requires further research. * Robert Hahn is professor and director of economics at the Smith School at the University of Oxford, a non-resident senior fellow at Brookings, and a senior fellow at the Georgetown Center for Business and Public Policy. Robert Metcalfe is Postdoctoral Research Scholar in Economics at the University of Chicago. We would like to thank Ted Gayer, Jonathan Hall, Scott Kominers, Jonathan Meer, Alex Teytelboym, Scott Wallsten, and Cliff Winston for helpful comments and Julia Schmitz, Brian Campbell and Samantha van Urk for excellent research assistance.

  • Wikis Supporting PLM and Technical Documentation Nils Høimyr, Peter L
    Wikis supporting PLM and Technical Documentation Nils Høimyr, Peter L. Jones, CERN, European Organization for Nuclear Research, Switzerland Abstract Over the last years, Wikis have arisen as powerful tools for collaborative documentation on the Internet. The Encyclopaedia Wikipedia has become a reference, and the power of community editing in a Wiki allows for capture of knowledge from contributors all over the world. Use of a Wiki for Technical Documentation, along with hyper-links to other data sources such as a Product Lifecycle Management (PLM) system, provides a very effective collaboration tool as information can be easily feed into the system throughout the project life-cycle. In particular for software- and hardware projects with rapidly evolving documentation, the Wiki approach has proved to be successful. Certain Wiki implementations, such as TWiki, are project-oriented and include functionality such as automatic page revisioning. This paper addresses the use of TWiki to document hardware and software projects at CERN, from the requirements and brain-storming phase to end-product documentation. 2 examples are covered: large scale engineering for the ATLAS Experiment, and a network management software project. .1 Introduction CERN is currently reaching the installation and commissioning stage of the Large Hadron Collider (LHC) accelerator project as well as the completion of the LHC Experiment Detectors (ATLAS, ALICE, CMS and LHCb) “large as cathedrals”. Along with the Accelerator and Detector hardware, there is the LHC Computing Grid project LCG, to build a worldwide computing grid to allow for simulation and analysis of all the data from the LHC physics experiments by physicists scattered all over the world.

  • Studying Abroad in Costa Rica
    Studying Abroad in Costa Rica By Joel Winters Travel Tips 1. DO NOT PACK LIGHT a. Bring a lot of comfortable clothes 2. Purchase a flight ticket back to the US within a 90 day period and cancel upon your arrival (some airlines will claim you need a VISA but you don’t and this will help with that) 3. DO NOT FORGET YOUR PASSPORT a. Make copies of your passport and license 4. Pack toiletries, sunscreen, and any of your favorite snacks in a CHECKED BAG a. Sunscreen costs about 15$ USD for a bottle in Costa Rica 5. Exchange USD for colones, have a debit card, and an emergency credit card Arrival Guide You will arrive at Juan Santamaria International airport (SJO), then you will have to go through customs. Show the customs officer your passport, destination, and answer any questions they ask. It is better not to talk unless they ask you a question. It only took me 10 minutes to get through customs but it can take more than an hour at some times. Next you will collect your bags and head out to find your host family (they will have a sign with your name on it). It is helpful to know basic Spanish because the host family will most likely not speak English. If they are talking too fast for you to understand it is okay to ask them to speak slower. I knew many people in the study abroad program that did not know any Spanish at all so knowing the language is not necessary to study abroad but it will make your adjustment easier.

  • Wikis As a Tool for Collaborative Language Learning: Implications for Literacy, Language Education and Multilingualism
    ISSN 2335-2019 (Print), ISSN 2335-2027 (Online) Darnioji daugiakalbystė | Sustainable Multilingualism | 5/2014 http://dx.doi.org/10.7220/2335-2027.5.8 Selami Aydin Balikesir University, Turkey WIKIS AS A TOOL FOR COLLABORATIVE LANGUAGE LEARNING: IMPLICATIONS FOR LITERACY, LANGUAGE EDUCATION AND MULTILINGUALISM Summary. This study presents a review of the literature concerning the use of wikis as a tool for collaborative learning in the second language acquisition and foreign language learning process, as research on the use of wikis is relatively new. The study first introduces the theoretical background behind the use of wikis in the mentioned processes. Then, it reviews the studies concerning wikis as a tool for collaborative language learning. The study concludes that the use of wikis improves basic language skills, encourages positive perceptions of learning, increases motivation, provides opportunities to practice autonomy, and enhances inquiry learning and critical thinking, although they appear to have no effect on cultural proficiency. More importantly, Wikis appear to be an advantageous tool for improving writing, and may have additional benefits in developing literacy in multilingual contexts where access to minor languages in the educational process is limited. The paper ends with practical recommendations for teachers and researchers. Keywords: collaborative learning; collaboration; foreign language learning; learner autonomy; second language learning. Introduction Within the contexts of second language acquisition and foreign language learning, wikis constitute a quickly emerging and popular learning tool. Because research on their efficiency is relatively new, wikis’ efficacy in the language acquisition and learning processes remains an open question. This study aims to review various scientific studies on the use of wikis as a tool for collaborative learning and their role within second language acquisition and foreign language learning contexts.

  • Using Wikis in Software Development
    open source Editor: Christof Ebert ■ Alcatel ■ [email protected] Using Wikis in Software Development Panagiotis Louridas In only a few years, wikis have become one of the most popular tool shells imaginable based on open source software. You can find them just about everywhere that demands effective col- laboration and knowledge sharing at a low budget. Wikipedia has certainly enhanced their pop- ularity, but they also have a place in intranet-based applications such as defect tracking, re- quirements management, test-case management, and project portals.

  • A Feasibility Study of a Bike Share Program (Bsp)
    A FEASIBILITY STUDY OF A BIKE SHARE PROGRAM (BSP) ON THE UNIVERSITY OF ALABAMA CAMPUS by JUDITH NTOW OPPONG SETH APPIAH-OPOKU, COMMITTEE CHAIR JOSEPH WEBER STEVEN JONES A THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in the Department of Geography in the Graduate School of The University of Alabama TUSCALOOSA, ALABAMA 2019 Copyright Judith Oppong 2019 ALL RIGHTS RESERVED ABSTRACT This thesis sets out to examine how feasible a bike share program will be at the University of Alabama (UA). Three case studies of campus bike sharing programs across the United States are used to show the different bike sharing systems in existence. The advantages of a bike sharing program are highlighted to show how the system can offer alternative transportation to the university campus. The current status of bicycle uses on University of Alabama campus as well as policies put in place are also discussed. The last part of the thesis applies lessons learnt from the case studies and evolution of bike share to a feasibility study for UA campus. ii ACKNOWLEDGEMENTS My heart felt appreciation to our Lord God who has showered on me blessings, knowledge and understanding to reach this academic ladder. My sincere appreciation to my thesis committee members especially Dr. Seth Appiah-Opoku (chair), for their selfless contribution to the success of this work. Thank you for not giving up on me even when I didn’t know what I was doing. My appreciation also to the Director of the Transportation Services for his contribution towards this study.
